As mentioned in A10 EMIF UG, looking for information on the following statement:
"Contact Intel FPGA Technical Services for information on how to manually trigger or inhibit periodic OCT updates for applications that are sensitive to latency."
Please share the solution so I can enable my customer. Thank you,
Hi, the GUI only lets permanently enable or disable Periodic OCT Calibration. What we need is the ability to selectively block it during critical data transfers and then re-enable it the rest of the time to compensate for temperature cycling, etc ...
According to 3.4.3: https://www.intel.com/content/www/us/en/programmable/documentation/eqw1503946000045.html#mhi14605679... there is a way to do this, but requires your support. My local Intel resource indicated some lower level code may need changing to expose the appropriate controls.
There is file to control the periodic OCT update and you can tweak the oct_recal_req signal in the file to enable or disable the periodic OCT.
